the examined substrates were transformed, mainly by 7α-hydroxylation. Studies carried out with M. silvaticus demonstrated the versatility of this organism in introducing hydroxyl groups at the 7α-, 9α-, 11α-, and 14α-positions in 3-ol-5-ene steroids. The relationships between the substrate structures and hydroxylated positions are also discussed.

modifying theA ring has been developed. It is established that the yields of the main and the side products greatly depend on the transformation conditions, mycelium age, and the structure of the steroid substrate. Under the optimal transformation conditions novel 9α-hydroxysubstituted derivatives of androstenolone, pregnenolone, 16-dehydro-16α,17α-epoxy-, and-16α-methoxypregnenolone have been obtained
